Hi,
It seems I got extra #Text node in my DOM object. For example, if my XML is as follows:
<Root>
<FirstElement>Value</FirstElement>
</Root>
My DOM tree will look like:
+ ELEMENT: Root
+ #TEXT:
+ ELEMENT: FirstElement
+ #TEXT: Value
+ #TEXT:
Is there a way to avoid those extra empty #Text Node?
//Create a DocumentBuilderFactory
DocumentBuilderFactory factory =
DocumentBuilderFactory.newInstance();
//Set the factory object to be validating
factory.setValidating(true);
//Set the factory object to not parse empty text nodes
factory.setIgnoringElementContentWhitespace(true);
//Create a DocumentBuilder and parse XML document
DocumentBuilder builder = factory.newDocumentBuilder();
Documentdocument = builder.parse(new File("input.xml"));
Those are not "empty" text nodes, they have newlines in them.
If your XML was:
<Root><FirstElement>Value</FirstElement></Root>
you would not see them. By default, you get them. As pointed out, you can ask the parser to ignore them.

In fact if you specified Xerces as parser / schema factory, you will get a new line.
System.setProperty("javax.xml.parsers.DocumentBuilderFactory", "org.apache.xerces.jaxp.DocumentBuilderFactoryImpl");
System.setProperty("javax.xml.validation.SchemaFactory:http://www.w3.org/2001/XMLSchema", "org.apache.xerces.jaxp.validation.XMLSchemaFactory");
I don't see how it could be a bug. The source XML file had newlines in it. Therefore a true representation of the content would include those Text entries.
Don't confuse "It does something that I don't want (at least for now)" with "it is not working as it was designed."

d.patterson setIgnoringElementContentWhitespace() is to ignore whitespace that is not a significant part of element content. I think that Extra #Text nodes aren't a significant part of element content.
And if to validate with DTD(!) this Extra #Text nodes aren't appeared. But if to validate with XSD(!), they are... And now you think that it isn't a bug?
